Slippery Extreme Anti-Icing Surfaces

Slippery Extreme Anti-Icing Surfaces

Anti-icing surfaces play a critical role in our everyday lives, maintaining the safety and reliability of systems in transportation, infrastructure, and energy. Non-wetting surfaces ('superhydrophobics') and liquid-infused surfaces have inspired routes for the development of the next generation of icephobic surfaces. However, high freezing temperatures, high ice adhesion strength, and low durability have restricted their practical applications. Here, we report new magnetic slippery surfaces (MAGSS) outperforming state-of-the-art icephobic surfaces with a ice formation temperature of 34 C, 2–3 orders of magnitude higher delay time in ice formation, extremely low ice adhesion strength (2 Pa), and stability in shear flows up to Reynolds number of 10^5.
